Cunningham St Northcote residential project made brighter with LoE-i89

A seamless combination of heritage and modern elegance sums up this two story Northcote home extension which is certainly easy on the eyes. And we are chuffed to see how well LoE-i89 has brightened it up – while still maintaining superior insulation. In fact it has been built using 80m2 of LoE-i89 glass and despite opting for toughened 6mm single glazed, it has been awarded a 6-star energy rating. This is because LoE-i89 is the only soft coat low-e glass of its kind able to achieve such performance, even as a single glazed unit.

Installed by glaziers Aztec Windows, the LoE-i89 glass is super clear and haze free other like other likeminded low-e products and looks even better with the black aliminium frames which slot in beautifully with the other materials selected.

This extension is collaboration between Bellemo & Cat architects, Build Her Collective and Beirin Projects and respects the existing heritage building with spectacular soaring pitched ceilings and floor to ceiling windows which flood the space with light. Other materials employed include polished concrete and engineered oak floors as well as marble, oak and black steel completing the bespoke kitchen which connects to the open plan living and private garden with a pool – all of which can be admired from inside and out.

While this energy efficient residence features zoned air conditioning and slab heating, we predict it won’t be overly used as the LoE-i89 works to keep the internal glass surface temperature and thus inside air temperature near constant year round.

SEFAR®’s versatility highlighted at Jackalope Hotel

Glassworks is chuffed to see its very own SEFAR Architecture Vision mesh laminated glass used in another new and interesting way at the Jackalope Hotel in Victoria’s Mornington Peninsula wine region.

Designed by Carr, the 46-room hotel is set on the renowned Willow Creek Vineyard. This new build compliments an existing winery, cellar door and Edwardian homestead – now the hotel bar.

Surrounded by acres of immaculate vines and rural native vegetation, Jackalope operates as a hotel, a function space, a restaurant and cocktail bar, and is truly redefining luxury among Victoria’s few boutique designer hotels.

Of course creating a unique visual-sensory, design-driven experience requires the combination of unique materials and ideas. What is certainly projected throughout the project is the meticulous attention to detail and design passion – from the 30 metre infinity pool through to the 9,000+ light bulb ceiling display to name a few.

With the hotel predominately clad in dark zinc with charred timber and black metal detailing, the SEFAR mesh laminated glass makes for an impactful staircase and second floor balustrade material.

SEFAR is a quality aluminium mesh from Switzerland exclusively laminated between two panes of glass by Glassworks in Australia. It is available in Aluminium (raw) or Printed Gold/Copper in various densities for different looks or levels of privacy. The Jackalope project used Printed Gold in density 140/50 with a soft LED lighting across the top of the panel to subtly bring out the gold flicker of the mesh in the glass, creating a bold highlight and yet another interesting visual element.

LoE-366 shines at Eastland Restaurant district

The multi-million dollar expansion of Eastland Shopping Centre completed in October 2016 has successfully taken this already expanded urban shopping centre to the next level as a destination to not only shop but also eat, drink and meet.

With the vision of transforming Eastland into one of Melbourne’s most progressive and exciting urban leisure destinations, in addition to the revamped retail experience, a new town square lined with signature restaurants, contemporary al fresco dining and a generous public space was incorporated into the project.

Paramount to the al fresco dining was marrying the indoor and outdoor environments which required an extensive use of glass. Probuild (tier 1 builders) opted for Glassworks’ LoĒ³-366 ® low-emissivity (low-e) glass for a number restaurants exposed to direct sunlight at certain times of the day. Because LoĒ³-366 delivers the ideal balance of solar control and high visibility, it was the perfect choice for restaurants such as Mexican street food eatery Paco Taco, cafe Brioche and steak restaurant Hunter and Barrel.

Historically, tinted glass would have seemed the only solution for an almost all glass front exposed to direct sunlight, although this would not have spoiled the view from inside and compromised visibility from outside. LoĒ³-366’s pioneering triple layer of silver actually far outperforms tinted low-e insulated glass units (IGU), achieving a Solar Heat Gain Coefficient (SHGC) of only 0.27 compared to 0.67.

On the aesthetic side, it was also chosen for its low reflectivity, producing an exterior reflectance of just 11% compared with 17% of a regular low-e IGU, as well as the ability to stay clean naturally thanks to the added Neat® easy-clean coating which harnesses the sun’s rays to lift the dirt so the rain can wash it away.

The best aspect of LoĒ³-366 is enjoyed during the hottest months as its sun blocking ability means less reliance on air conditioning for enhanced occupant comfort and energy savings.

SolarAdapt beats heatwave

Glassworks’ SolarAdapt glass proved why it is the ultimate heat controlling, energy saving products of its kind during an Australian summer heat wave.

As temperatures soared above 40 degrees in Melbourne this summer, the Glassworks head office commissioned an engineer to measure the actual performance of their building, including their new SolarAdapt glass range.

“The SolarAdapt Solar Responsive Thermochromic (SRT) technology uses the sun’s own energy to cause the tinting of the window,’ says Michael Gleeson from Glassworks. ‘As the sun strikes the window it absorbs and adapts the tint level based solely on the amount of direct sunlight, thereby reducing heat gain.”

The results from the commissioned experiment were encouraging for the Glassworks team, and the engineer’s performance report suggest the same.

The reports found that when the outside ambient temperature of 42.5 degrees Celsius hit at 3:30pm, the external glass temperature rose to 77.3 with the internal glass temperature being 33.5. This enabled the building to be air conditioned at around 24 degrees C as normal.

“A Solar Heat Gain Coefficient (SHGC) of a mere 0.07 was also reported at this time, compared with a SHGC of 0.58 for commonly installed 6mm Grey tinted glass,” Gleeson reports.

Can the right type of glass provide energy efficiency? The Whitepaper

Choosing the right type of glass is becoming more and more than just about the clarity and aesthetics.

With up to 40 percent of a home’s heating lost, and more than 87 percent of it gained through windows alone; the thermal performance in glass is a crucial element to consider when cutting down on energy costs and consumption.

The right type of glass possesses the unique ability to retain heat in the winter, all the while ensuring that a building is also kept cool in the warmer months. The challenge is then balancing this thermal performance with the clarity and the ability the let in natural light, to further save energy not only of cooling and heating loads, but also minimising artificial lighting.

We have developed a Whitepaper examining in detail how glass gains and loses heat and the emergence of low-emissivity glass and the options available to improve a building’s energy efficiency as well as provide comfort and health benefits for building occupants.

High Distinction for LoE-366 at the Australian Catholic University

While denoting an environment of research, study and the Catholic identity, the 4,000m2 space is “welcoming, inclusive and invites people to stay,” says Jeroen Hagendoorn, HASSELL’s Lead Architect on the project. 

Taking its distinct design cue from the structure of the former 1920’s bank note facility, Schiavello completed the industrial-natured refurbishment in four stages. This included the lower ground, ground floor and addition of a six-storey external staircase enclosed in a glazed facade. Making the first impression from the exterior, Glassworks supplied their pioneering LoE-366® low-emissivity glass in 6mm – becoming more and more recognised for it’s solar control and high visibility.

Making up such a significant portion of the exterior, LoE-366 really was a wise choice as it means occupants can enjoy a more naturally temperature controlled building with less glare and full view from the inside out – all conducive to studying and concentration. The client can also enjoy reduced electricity costs and less cleaning thanks to the added Neat® easy-clean coating.

Featuring open batten ceilings to reveal exposed structural and services elements, a new reception, security office, bookstore, cafeteria and lounge areas – all newly constructed for the open space. The lower ground also incorporates a new state-of-the-art radio room, Student Council Office, Facilities Department amenities and mail room. Utilising a neutral palette of stone and timber, the highly durable materials were chosen to weather high traffic use. Glassworks were pleased to be engaged for works on the external staircase which additionally embraces the building’s original window fenestration.

The new ground floor also maintains the building’s heritage integrity by replacing existing aluminium framed windows with steel frames created by Schiavello subsidiary, Metcon.

Bairnsdale Library using LoE-366 glass

Designed by NOWarchitecture, the Bairnsdale library project completed in 2015 was acknowledged by the design and building industry at several award programs. The project was named the winner of Best Commercial Building ($3M-$6M) in the 2015 Master Builders Regional Building Awards, a finalist for two categories in the Australian Timber Design Awards, two categories in the Australian Property Institute Awards, and the Banksia Sustainability Awards.

The project brief required the design to uphold the connection to the Heritage Hall, which ran along the full length of the northern edge of the site, taking up the entire desired northern aspect. Since NOWarchitecture chose to make use of the east facing glazing on the front facade, the glass performance was critical to the success of the design.

Glassworks’ LoE-366 provided the best combination of insulation, natural daylighting and transparency with low reflectance. In combination with the timber structure and the Raico Therm + glazing system, the LoE-366 delivered an extremely high value system, with higher insulation levels and lower cost than conventional aluminium facade systems.

The Bairnsdale library also serves as a community hub with meeting rooms, a cafeteria and a range of formal and informal reading and research spaces. The innovative and holistic environmental design has reduced operational and energy costs, providing a warm aesthetic based on exposed plantation timber structures. The high performance of the LoE-366 glass facade atrium and a passive hydrothermal air conditioning system combine to provide excellent natural lighting, thermal comfort and air quality.

The glazing system was a crucial factor in the success of the building design by providing a facade with a U value of 1.36 while allowing high levels of natural lighting. The excellent transparency of the facade design plays a key role in engaging the public and in the aesthetic response to the heritage building. The high level of visibility into the building from the street and the use of LED internal lighting not only secure the plaza forecourt but also promote the library at night.

Product and material selections for the project were based on value for money both in construction and ongoing costs. For instance, joinery quality allowed secondary finishes to be significantly reduced, saving costs and increasing value; the glazing system incorporates approximately 140m² of performance LoE-366 glass; the timber framed, double glazed facade ensures higher daylighting levels and lower heat gain and loss. Once up and running, the client monitored the energy usage at the library observing significant reductions; and LoE-366’s Neat® easy-clean coating is practically self-cleaning, reducing ongoing maintenance.

“Though low-emissivity glass such as LoE-366 glass is already being adopted across Europe and America, the fantastic result of the Bairnsdale Library could well be an Australian landmark project, demonstrating the performance and aesthetic potential of this low-E glass”, says Glassworks General Manager, Michael Gleeson.
